CONSTRUCTION OF CAR-TRUCKS.

Application filed April 9, 1897, Serial No. 631,473.

To all whom it may concern:

lle it known that we, RANsoM C. lVRiGI-rr and FRANK E. STEBBINS,citizens of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, and at l/Vashington, Districtot' Columbia, respectively, have invented certain new and usefulImprovements in the Construction of Car-Trucks; and we do declare thefollowing to be a full, clear, and exact description ot the invention,such as will enable others skilled in the art to which it a ppertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form a part ot'this speci tication.

The object of our invention is the produclion of a car truck which shallhave the transoms and sides made of metallic beams preferably flangedand of channel section, and the pedestals of cast metal; which shall bestiff and rigid at the points where the transoms join the sides; andwhich in one example shall have one leg of each pedestal removable sothat a pair of wheels, an axle, and the journal boxes may be rolled outat the end ot' the frame when the weight is taken ott the springs, whensprings are used, and without removing the entire frame from the pairsof wheels and axles.

Our invention consists in a car truck having metallic side pieces andtransoms with bent or turned ends extended over the journal boxes.

Further, it consists in a car truck having atthe ends inner pedestallegs extending under the ournal boxes, spring pockets, and outerpedestal legs which are removable.

Further, it consists in a car truck having at the ends inner pedestallegs, and outer pedestal legs the upper end of each of which is securedin place by two or more bolts.

Finally, it consists in certain novelties of construction andcombinations of parts, especially relating to the pedestals, receptaclesabove the journal boxes for the springs, and the end portions of theframe, as hereinafter set forth and claimed.

The accompanying drawing illustrates one complete example otI thephysical embodiment of our invention relating to the frame, and twomoditied examples of the pedestal and end trame constructions, allconstructed according to the best modes we have so far Specification ofLetters Patent.

devised for the practical application of the principles.

Figure 1 is a side View in elevation of the complete truck. Fig. 9. is atop plan view ot' Fig. l. Fig. 3 is a section on line lll-1V. Fig. 4t anend view oit' the pedestal, Fig. 1, in elevation. Fig. 5 is a section online UU. Fig. (3 is a view ot a journal box. Figs. T and 8 are side andend views of a modified construction of the pedestal and end oit theframe. Figs. 9 and 10 are side and end views of another inodilication ofpedestal and end trame construction.

Referring to the figures of the drawing, and especially to Figs. 1 to(i, the number 95 designates the metallic side pieces of channel shapeis cross section, and 96 the transoms extending across the truck framebetween the pairs of wheels and thereafter parallel with and to the samedistance as the side channel pieces, these transoms being also ofchannel shape in cross section. The outer pedestal legs are removable,the leg 10S extending downward from the frame and thereafter outwardlyand under the axle box 115 and united by bolt 108, to the removable leg112, said leg 112 extending upwardly and being secured between the sidepiece 95 and the piece 96 by removable bolts 113; the leg 10S also issecured between and to the side piece 95 and piece 9G by rivets 109, thetop horizontally extended part of the same being cut away at its lowercentral surface above the axle box to form a spring bearing surfacewithin the pocket.

The side channel 95 and the side 90 are pressed outwardly, as shown at110 and 111, Fig, 3, which is a section on line lV-lV, Fig. 1, to Jr'ormabout a half pocket in each, and tlanges 109 are formed to bear underthe lower flanges ot' the channel side pieces. At the opposite end ofthe track, Fig. 1, is a similar lixed leg 102 extending downwardly fromthe frame below the axle box 1141, secured to swing leg 105 by bolt 11S,having its upper part located between t-he side channel 95 and channel90 and held in position by rivets 103, tlanges 1011 being provided belowthe lower flanges of the side trame pieces, and half spring pockets 110,111 being formed for the reception of a spring and by pressing out themetal of the channel beams. The swing leg 105 is hinged by a bolt 107,and is locked by bolt 10G as well as by bolt 118, the dotted lineshowing the position of the leg when swung upwardly to allow the removalof the boxes 114.

To facilitate the removal of the axle boxes 114, 115, the springs will,when in use, be held only upon their inner and outer sides by the ribs115, as shown in Fig. 6. This permits the box to move outwardly underthe spring when the spring is released of its load. Transoms 96 arestill further secured to side channels 95 by the double headed T pieces,a section of which taken through line U-U, Fig. 1, is shown in Fig. 5,where it will be seen to engage the insides of the webs'and the upperand lower flanges of the side channel pieces and traiisoins and securedby rivets 9S. The transoms and side pieces are further held together' bya gusset plate 99 at the top and a gusset plate 99 at the bottom andsecured to the flanges of the channels by rivets 100, 101 and 101. Sidebearings 119 are secured to the gusset plates by rivets 120, and acenter plate 121 is riveted to the transoms 96 by the rivets 122.

Figs. 7 and 8 show a modification of a pedestal and end frameconstruction wherein both legs are stationary and fixed. These legs 123,124 extend vertically downward from the frame on either side of the axlebox 133, being united below by tie piece 131 secured by bolts 132. Theends of the side frame are designated by 125 and 126 and each is pressedoutwardly directly above the axle box to form a spring pocket 140 inwhich is located spring 139. Below the lower flanges of the end frameflanges 124 and 125 are formed on legs 123, 124 which bear against theflanges of the channels. T he legs extend upwardly into the spacebetween the channel pieces at each side of the spring pocket 140, thenbroaden into flanges 129 above the upper flanges of the side frame, andabove the channels is an arched stifl'ening rib 123, all being securedto the frame by rivets 127 and 130.

Figs. 9 and 10 show a second modification of construction with aswinging pedestal leg at the outer side. The numbers 143 and 144 are theends of the side frame, 134 the fixed leg having under flanges 135 belowthe side frame, which leg at its upper end is located between thechannels and broadens into ribs 147 above the upper flanges of the frameand has an arched central stiffening rib 146. The leg at the top extendsdownwardly beyond spring pocket 142 into the space between the sidechannels and is secured by rivets 145, 148. The leg 134 extends underaxle box 150 and is joined to a swinging leg 137 by a bolt 136. This leg137 is hinged between the side pieces 143 and 144 by a bolt 138. Axlebox 150 will be provided with spring ledges or ribs 115', as shown inFig. 6, to facilitate the removal of the box.

From the foregoing description taken in soms join the sides, and thepedestals, or

parts thereof, may be easily replaced should the same become broken. `fehave shown in Fig. 1 the removable pedestal legs each secured in placewithin a slot in the frame at the top end by two bolts. The advantage ofthis arrangement is clear, for the reason that should the lower end ofthe pedestal leg become detached or loose the two upper bolts will bytaking the strains imparted by the journal box in opposite directionshold the leg in place. These bolts can, of course, be located in anyposition so long as they perform the desired functions. However', theouter legs may be made simply detachable and not pivoted to swing whenso desired, as shown at the left in Fig. 1, where the upper end isangular.

7e have also illustrated the spring pockets inthe modified examples asextending the full depth of the beams, whereas in the main view they aresomewhat more shallow. The depth of the pocket may be varied to suitconditions and, when desired, may be extended above the side pieces.

Various modifications may, of course, be introduced in practice whichwill not constitute substantial departures.
